UNITED STATES WILLIAM S. AUGHINCLOSS, OF WILMINGTON, DELAWARE.

IMPROVEMENT IN RAILWAY-CAR AXLE-BOXES.

Specification forming part of Letters Patent N o. 121,572, datedDecember 5, 1871.

To all whom it may concern:

Be it known that I, WILLIAM S. AUcHrNcLoss, of Wilmington, in the countyof New Castle and State of Delaware, have invented a new and usefulImprovement in Axle-Boxes for Railroad Gars; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawing forming part of thisspecification, in which drawing- Figure l represents a front view ofthis invention. Fig. 2 is a sectional side View of the same. Similarletters indicate corresponding parts.

This invention consists in the arrangement of a strap of wronghtiron,steel, or malleable iron extending round an axle-box and round the lugorear projecting from said box, and forming the bearing for the pin thatconnects the equalizing beam with the axle-box in such a manner that theequaliZing-beani will be securely supported beneath the axles of thecar, and consequently the height of the center of gravity above the railis materially reduced.

In the drawing, A A designate the two axleboxes, which are connected toone and the same equalizing-beam B. This equalizing-beam is situatedbeneath the axles of the car or truck, and it is connected to theaxle-boxes A A by means of pins a a passing' through lugs b bf, whichare cast solid with the boxes. The strain produced by theequalizing-beain on the lugs b b is downward, and in order to strengthenthese lugs, and to enable them to support the equalizing-beam withoutdanger of breaking or splitting, I have applied to my box a strap, C,made of wroughtiron, steel, or malleable iron, `and passing round thebody of the box and round the lug or ear b or b,`as shown in thedrawing'. This strap may be cast in or on, or shrunk on or attached inany other desirable lnanner, and it must be made sufficiently strong topreclude all danger of breakage. 0n some of the boxes l have two lugs,as shown in Fig. 2, both being strengthened by straps; and in this casethe end of the equalizingbeam passes-in between the two lugs. When thebox is provided with one lug the end ofthe equalizing-bealn is madebifurcated, so that it will straddle the lug, as shown on the box A',Fig. l.

By this construction of the boxes I am enabled to place theequaliZing-beam beneath the axles,

and by thus reducing the height of the center of.

gravity from the rails the steadiness of a car in motion is materiallyincreased7 an advantage which is of particular value for narrow-gaugeroads.

I do not conline myself to the use of the lug or lugs, but can, when itseems desirable, increase the depth of the strap, and thus form abearing or body for the pivot.

That I claim as new, and desire to secure by Letters Patent, is-

The arrangement on an axle-box of a strap or straps, C, embracing thebody of the box and the lug which forms the bearing for the pivot of theequalizing-beam, substantially as set forth.
